8cm tailpipe diameter should give approximately 4cm on the augmentor diameters. The augmentor length is probably near 32cm. Not sure how reducing the intake diameters will affect it, but should be close enough to see considerable thrust improvement. Also let us know if the sound increases from adding the augmentors.

ok then i will make the augmenters fix it,test it and update it here. Waiting for the gas tank.

an important thing shall i place the augmenter at a distance of 6cm from the intake pipe or more than 6cm.

Hello everyone here is the engine i have fixed to my bicycle its a 13pounds thrust engine. Today i tested the engine with 14.2kg of gas got some enormous power cant hold it pushes so hard. For now only pictures and i will post the video as soon as possible.

Fixed the augmenter to my engine and result was this, take a look at the video. i dont know whether its powerful or not because i didnt hold the bicycle, but my mom told that she wasnt able to hold the cycle because it was pushing so hard. But according to me the sound(noise) was too much than before.

Good work on it, I wasn't sure how to calculate a augmentor with that intake/tail diameter. Looks like you estimated it close. The augmentors could have 37cm more length added to the back if you need a little more thrust. You can see the flame pulsing out the back of the augmentors.

Be careful, those intakes are just below where your body would be sitting, and if a pulse stopped the flames from the intake could burn thighs, calves, and feet. Make sure you can shut off the fuel quickly. Always do a technical inspection and check for lose fuel connections or leaks or any multitude of things that could fail.
If you must ride it, apply water to your hair and clothing. As metiz advised shielding would help considerably.
